Understanding bitumen stabilised materials

A new technical guideline document for the design and construction of bitumen stabilised materials was published by the Asphalt Academy in South Africa in May 2009. Entitled “TG2, 2nd Edition, Bitumen Stabilised Materials”, this publication is the culmination of a massive effort by both researchers and practitioners to understand these materials and develop appropriate design tools. By doing so, this publication promises a new dawn for bitumen stabilised materials. Some myths concerning performance are exposed and, most importantly, the competition between the bitumen emulsion and foamed bitumen lobbies is addressed by placing both on the same footing. This paper focuses on the results of research carried out over the past decade, coupled with long-term pavement performance data that were used to understand the in-service behavioural characteristics of these materials and their failure mode. The resulting new design methodology is reviewed along with the adoption of a heuristic modelling approach to obtain reliable indicators of performance. A final section summarises the economic and environmental benefits that accrue from using these materials. (a) For the covering record of the conference, please refer to ITRD no. E218387.
